Hadith text
Narrated Abu Juhaifa:I came to the Prophet (ﷺ) while he was inside a red leather tent, and I saw Bilal taking the remaining water of the ablution of the Prophet, and the people were taking of that water and rubbing it on their faces; and whoever could not get anything of it, would share the moisture of the hand of his companion (and then rub it on his face)
Abu Juhaifa bataate hain: Main Nabi (SAW) ke paas aaya jabke wo ek laal chamde ke khaime mein the, aur maine Bilal ko Nabi (SAW) ke wuzu ka baacha hua paani lete dekha, aur log us paani ko lekar apne chehron par malte the; aur jo koi kuch na paata, wo apne saathi ke haath ki namee se hi (kaam chalaakar apne chehre par malta).
